Reoperation after primary operation for pre-axial polydactyly of the hand: A 12-year experience at a single institute.

Background: This study aimed to evaluate and describe the rate, reasons, and detailed procedures of reoperations for pre-axial polydactyly of the hand at our institute conducted within 12 years.

Methods: We retrospectively reviewed the medical records and radiographs of 268 patients (292 digits) with pre-axial polydactyly of the hand, who were treated surgically at our institute from November 2006 to May 2018 and followed up for >12 months.

Results: Fifty-two thumbs of 47 patients underwent reoperations, yielding a 17.

Excision of Rudimentary Preaxial Polydactyly of the Hand with Use of Electrocautery.

Background: Suture ligation has been used widely for the treatment of rudimentary type extra digits, but several complications related to this treatment have been reported. The purpose of this study was to describe a new technique for excision of rudimentary preaxial polydactyly of the hand using electrocautery and assess its clinical outcomes.

Methods: The authors performed a retrospective study of 34 thumbs (32 patients) that had undergone excision of rudimentary preaxial polydactyly using electrocautery under local anesthesia.

Sea Fog Dissipation Prediction in Incheon Port and Haeundae Beach Using Machine Learning and Deep Learning.

Sea fog is a natural phenomenon that reduces the visibility of manned vehicles and vessels that rely on the visual interpretation of traffic. Fog clearance, also known as fog dissipation, is a relatively under-researched area when compared with fog prediction. In this work, we first analyzed meteorological observations that relate to fog dissipation in Incheon port (one of the most important ports for the South Korean economy) and Haeundae beach (the most populated and famous resort beach near Busan port).

Effect of pre-treatment expectations on post-treatment expectation fulfillment or outcomes in patients with distal radius fracture.

Background: The influence of patient expectations on patient-rated outcomes (PRO) after elective orthopedic procedures has been addressed in previous studies. However, the influence of pre-treatment expectations on post-treatment PRO was rarely examined in patients with extremity fractures.

Purpose: The purpose of this study was to determine if pre-treatment expectations have an effect on post-treatment expectation fulfillment or PRO in patients surgically and conservatively managed for distal radius fractures (DRFs).

Polydactyly of the thumb: a modification of the Wassel-Flatt classification.

Although the Wassel-Flatt classification system has been widely used for radial polydactyly, it has some limitations. We modified the classification system by introducing the hypoplastic types and refining the definition of triphalangeal thumb without changing the main structure of the original classification system. A total of 200 consecutive duplicated thumbs of 183 patients treated surgically from June 2016 to June 2018 were included.

Increased expression of macrophages and inflammatory cytokines at tendon origin in patients with chronic lateral epicondylitis.

Background: The success of anti-inflammatory medications and corticosteroid injections in controlling chronic lateral epicondylitis symptoms suggests an underlying inflammatory pathology that is also causative of the pain experienced by patients; however, evidence regarding inflammatory mediators and cells remains inconclusive.

Methods: We conducted a case-control study that included a total of 24 participants (10 patients and 14 controls). Extensor carpi radialis brevis tendon samples were obtained from patients, and flexor carpi radialis tendon samples were obtained from control subjects.

Lumbar Cryptococcal Osteomyelitis Mimicking Metastatic Tumor.

Cryptococcus is an encapsulated, yeast-like fungus that rarely causes infection in immunocompetent patients. We present the case report of a 66-year-old female patient with a history of rectal cancer with an isolated lumbar vertebral cryptococcosis proven by biopsy performed during operation. The patient was not an immunocompromised host and did not have any other risk factors except the history of cured rectal cancer.

Effects of cigarette smoking on hearing recovery from noise-induced temporary hearing threshold shifts in mice.

Hypothesis: Cigarette smoking may potentiate noise-induced hearing loss.

Background: Many epidemiological studies have shown that cigarette smoking is a major risk factor for noise-induced hearing loss.

Methods: BALB/c mice were exposed to passive smoking for 2 h/d for 2 weeks before exposure to 110-dB sound pressure level white noise for 3 hours once.
